Description
Technical field
The present invention relates to a kind of base structure for installing shaft tower, be specifically related to a kind of pre-stressed concrete pipe pile foundation
And construction method.
Background technology
The installation foundation form of the shaft tower such as shaft tower, electric force pole tower of communicating at present generally includes the pile tube of filling concrete form
Basis and the pipe pile foundation of steel-pipe pile form.Wherein the construction site of the pipe pile foundation of filling concrete form requires big, construction
Cycle is long, is not suitable for the region constructions such as both sides, urban road, scenic spot, park, square；Steel-pipe pile uses static pressure mode directly to press
Entering the end, ground, although it has short construction period, construction site requires little feature, but steel-pipe pile exists maintenance perishable, difficult
Problem.
Summary of the invention
The invention aims to overcome the deficiencies in the prior art, it is provided that one not only short construction period, execute
Work site requirements is little, can effectively solve that steel-pipe pile is perishable, the problem of difficult maintenance, and mounting stability is good, and beneficially bar
The pre-stressed concrete pipe pile foundation of tower installation and construction method thereof.
The technical scheme is that
A kind of pre-stressed concrete pipe pile foundation, including solid concrete stanchion and be positioned at the coagulation below solid concrete stanchion
Soil pile tube, in a tubular form, the upper end of concrete tubular pile is connected described concrete tubular pile with the lower end of solid concrete stanchion, coagulation
The lower ending opening of soil pile tube.
The pre-stressed concrete pipe pile foundation of this programme uses static pressure or the mode beaten to be pressed into the end, ground and is formed for installing
The base structure of shaft tower, its short construction period, construction site require little, and concrete tubular pile can effectively to solve steel-pipe pile perishable
Erosion, the difficult problem safeguarded.
On the other hand, owing to pre-stressed concrete pipe pile foundation top is solid concrete stanchion, so it is not only convenient for peace
Dress shaft tower, prior, when, due to the extruding of solid concrete stanchion at the press-in end, ground in pre-stressed concrete pipe pile foundation,
Soil layer immediately below solid concrete stanchion will be compressed to form more densely cross-linked support soil layer, the simultaneously soil in concrete tubular pile
Layer is compressed to form more densely cross-linked support soil layer too, thus the installation being effectively improved pre-stressed concrete pipe pile foundation is steady
Qualitative, it is to avoid pre-stressed concrete pipe pile foundation sinks.
As preferably, being provided with lower framework of steel reinforcement in concrete tubular pile, lower framework of steel reinforcement includes being arranged on concrete tubular pile
Doughnut-shaped steel plate on lower surface, some lower steel hoops being sequentially distributed from bottom to top in concrete tubular pile and some downward
The vertical prestressed reinforcement stretched, the lower end of described vertical prestressed reinforcement is connected with doughnut-shaped steel plate, vertical prestressed reinforcement
Upper end up extends in solid concrete stanchion.The vertical prestressed reinforcement of this programme is subject at pre-stressed concrete pipe pile foundation
The pressure of part can be offset during pressure, postpone the appearance in concrete tubular pile crack and carry out, being conducive to improving pipe of concrete
Crack resistance, rigidity and the impermeability of stake.
As preferably, being provided with framework of steel reinforcement in solid concrete stanchion, upper framework of steel reinforcement includes some depending on from bottom to top
The secondary upper steel hoop being distributed in solid concrete stanchion and some upper vertical reinforcements extended up and down.
As preferably, in the middle part of solid concrete stanchion, it is provided with the ventilative row of the both ends of the surface up and down running through solid concrete stanchion
Mud hole.Due to the setting of ventilative mudhole, during pre-stressed concrete pipe pile foundation is pressed in soil in concrete tubular pile
Air and mud can be discharged by ventilative mudhole, it is to avoid form pore in concrete tubular pile, it is ensured that in concrete tubular pile
The density of soil layer, thus improve the stability of pre-stressed concrete pipe pile foundation.
As preferably, solid concrete stanchion upper surface is embedded with some foundation bolts, and the upper end of foundation bolt in advance
It is positioned at the top of the upper surface of solid concrete stanchion.The installation of shaft tower is easy in the setting of foundation bolt.
As preferably, the side of solid concrete stanchion is embedded with suspension ring in advance.The setting of suspension ring is easy to loop wheel machine and will be answered in advance
Power concrete pipe pile foundation is sling.
As preferably, the lower surface of concrete tubular pile is provided with the annular pile top sheath of metal material, annular pile top sheath
Thickness be gradually reduced from top to bottom.Annular pile top sheath is possible not only to protect concrete tubular pile not damaged during pressure down
Bad, and press in soil layer owing to protecting concrete tubular pile.
The construction method of a kind of pre-stressed concrete pipe pile foundation, the lower surface of concrete tubular pile is provided with the ring of metal material
Shape tooth set, the lower surface of annular tooth set is the flank of tooth, and this flank of tooth has the double wedge of some continuous distribution；Prestressed concrete pipe pile base
The construction method of plinth comprises the following steps successively:
First, pre-stressed concrete pipe pile foundation sling and be placed into the appointment position on earth's surface；
Then, piling machine is used gradually to be beaten in underground layer by pre-stressed concrete pipe pile foundation.
During the pre-stressed concrete pipe pile foundation press-in end, ground, if run into gravel layer or hard weathered rock formation,
Then pre-stressed concrete pipe pile foundation will press construction under being obstructed and being difficult to.This programme improves for this problem, effectively solves
This problem.
This programme arranges annular tooth set in the lower surface of concrete tubular pile, and uses the mode beaten by prestressed concrete
Pipe pile foundation is gradually beaten in underground layer；At piling machine, pre-stressed concrete pipe pile foundation gradually beaten the process in underground layer
In, if running into gravel layer or time be obstructed in hard weathered rock formation, the pile monkey at piling machine clashes into pre-stressed concrete pipe pile foundation also
Mention this in a flash, owing to the flank of tooth of annular tooth set has the double wedge of some continuous distribution, at the flank of tooth of double wedge, (flank of tooth is oblique
Face) with under the gravel effect of gravel layer, pre-stressed concrete pipe pile foundation often produces a certain amount of skew and rotation, thus
Abolish gravel layer or the stop of hard weathered rock formation, make pre-stressed concrete pipe pile foundation to be beaten into appointment smoothly deep
In the soil layer of degree.
The invention has the beneficial effects as follows: not only short construction period, construction site require little, can effectively solve steel-pipe pile perishable
Erosion, the difficult problem safeguarded, and mounting stability is good, and beneficially shaft tower is installed.
